Abstract: A process for making a light hydrocarbonaceous liquid in a delayed coker comprising:(A) providing a hydrocarbonaceous feed to the coke drum and heating the feed to a temperature of about 800.degree. F. to about 1200.degree. F. to provide an intermediate product; and(B) introducing said intermediate product into the coke drum, operating the coke drum to convert the intermediate product to a final comprising light liquid and coke, and separating the light liquid from the coke;step (A) being conducted in combination with either step (A) (i) or step (A) (ii);Step (A) (i) comprising maintaining the feed during step (A) in an enclosed space and subjecting the feed to a pressure that is at least about 500 psig and is sufficient to maintain the specific gravity of the contents of the enclosed space at least about 0.

Abstract: This invention relates to a process for upgrading a hydrocarbonaceous material having an initial boiling point of at least about 625.degree. F. to a product having a lower boiling point than the initial boiling point of said hydrocarbonaceous material and/or a higher boiling point than the final boiling point of said hydrocarbonaceous material, the process comprising heating a mixture comprising said hydrocarbonaceous material and at least one organic solvent in an enclosed space in the absence of externally supplied water or hydrogen at a temperature in the range of about 750.degree. F. to about 1300.degree. F. and a pressure in excess of about 1200 psig for an effective period of time to yield said product, said pressure being sufficient to maintain the specific gravity of the contents of said enclosed space in the range of about 0.05 to about 1.

Abstract: The present invention provides a facile method of oil removal from an oil-water emulsion containing suspended solid particulates. In general, the method utilizes a volatile solvent which is liquefied under pressure and forms a two-phase system when in contact with the emulsion.

Abstract: A process is disclosed for separating an organic material from a composition comprising said organic material intermixed with particulate solids, the process comprising advancing a light hydrocarbon fluid through said particulate solids at an effective rate to drive said organic material from said particulate solids.

Abstract: A process is disclosed for separating an organic material from a composition comprising said organic material intermixed with particulate solids, the process comprising advancing a light hydrocarbon fluid through said particulate solids at an effective rate to drive at least some of said organic material from said particulate solids, adding water to said composition containing particulate solids and residual organic material to produce a second composition, and adding an oxidizing agent to said second composition in an amount sufficient to remove substantially all of the residual organic material.

Abstract: Method and apparatus for removing oil and other organic constituents from particulate, inorganic-rich mineral solids. The method and apparatus are particularly suitable for removing oil from oil-contaminated drill cuttings. The solids to be treated are transferred into pressure vessel means wherein they are contacted with an extractant which is normally a gas but is under conditions of pressure and temperature to provide the extractant in a fluidic solvent state for the constituents to be removed, whereby the constituents are transferred to the extractant. The extractant containing the constituents is withdrawn from the pressure vessel and depressurized to render it a nonsolvent for the constituents and to form a two-phase system which can then be separated into extractant for repressurizing and recycling with proper handling of the constituents removed.
